Uhm, which patch? I think that wasn't intentional, at least I can't
remember intentionally disabling period. Maybe I missed the subtle
change of behavior too.
I do see the point in having this configurable as this is a cpu overhead
vs. latency tradeoff which one might want to tweak depending on the use
case.
If we keep it we should pass it down to the audio backends I think.
pulseaudio for example uses buffer sizes adjusted for the default period
(see qpa_init_out()), when running with a non-default period pulseaudio
should be able to adjust the buffer sizes accordingly.
cheers,
Gerd
